NTIA Report TR-94-313Analysis of Electromagnetic Compatibility Between Radar Stations and 4 GHz Fixed-Satellite Earth StationsJuly 1994Frank H. Sanders, R.L. Hinkle, B.J. Ramsey |

Abstract: The susceptibility of 3700- to 4200-MHz fixed-satellite service earth stations to interference from radar signals, and the mechanisms by which such interference can occur, are examined. It is shown that interference can occur even if all currently applicable NTIA and FCC spectrum engineering requirements for radar emissions and earth station receiver systems are satisfied. It is further shown that while most interference problems can be resolved by installing appropriate radio frequency (RF) filtering on either the radar transmitter RF output or the earth station RF input, determination of the system that requires filtering depends critically upon the interference coupling mechanism. Methods for determining the interference coupling mechanism are presented. |
Keywords: audio receive-only (ARO) terminals, digital audio receiver terminals (DART), electromagnetic compatibility (EMC), interference coupling mechanisms, fixed-satellite earth stations, front-end overload, interference mitigation, low-noise amplifier, radar interference, radar spurious emissions, radar stations, television receive-only (TVRO) systems |
